Did you use the original X-Bracket from your previous card or you are using some other?
Can you post a photos of the card and the X-Bracket?
Do you see the HP logo on the initial boot screen and then the picture disappears or there is no any picture at all when you power up the laptop?
Do you have picture when connected via VGA/DP ports to external display?

 

Hi, thanks again for trying to help me here.

I removed the X bracket from the original an put it on the new Gtx 980m.

I have installed the old driver using DDU, then I installed the 980m card into the mxm slot and putting the heatsink back.

When I power the laptop back everything seems to be running as a normal fan running as usual but I can get any display on the screen.

No Hp logo comes up on the initial boot screen at all.

I've also tried to connect through VGA display on the external monitor to see if it works but with no luck.

Is there anything I'm doing wrong

Please see pictures

Everything seems right what you’ve done.
There is not other option, but to take the card out and try it in another system, just to be sure this is working card.
For now all is pointing at faulty graphic card.
Is there any mark on the GPU indicating its vBios version? Any numbers? Can you send me the pic of the graphic card on both sides without heatsink on it?
It might be a g-sync version (hardware ID 1617) of GTX 980m which will not work on HP 8770W (the right one has to have HW ID 13D7), but most probably is vBios incompatibility between the GPU and your laptop. First send me the photos of the card (both sides) without heatsink on it and then we will see what should be done next.

 

Mate your help is much appreciated.

As requested please see pictures below of the actual GPU and the link from where I bought the GPU through eBay where the seller confirms its compatible with HP EliteBook 8770w.

Is there any setting I need to change in the bios maybe??

You are very welcome!

Based on the photos, you have done in completely wrong way the arrangement of the thermal pads. They are way too thick for this setup. You need 1.5mm pads on every element (they must be soft thermal pads like Arctic). From the photos it seems the core have almost no contact at all with the heatsink, based on how the thermal compound has spread.
Please, remove all of the thermal pads for now, put less thermal compound on the core (rice and a half sized drop in the middle is enough) and tell me if the laptop boots normally this way (don’t worry there are no thermal pads on the vram and mosfets, this won’t hurt the card without intensive 3D tasks, which we will not use for now.

 

Ok, I will try again with your above recommended advice and keep you updated if this works.

Many thanks
